Thermal Receipt Fading Is a Real Compliance Risk
Pick up a receipt from the bottom of a bag that has been sitting there since last winter. There is a reasonable chance the text is already ghost-like, faded at the edges, or completely blank in patches. Leave it another year and there may be nothing readable left at all.
This is not a storage problem. It is a chemistry problem. Thermal paper works by coating the paper with a heat-sensitive layer that reacts when it passes through the printer. That same coating reacts to light, heat, humidity, and even the oils from your fingertips. Under normal conditions, thermal receipts begin degrading within 6 to 18 months. In a warm car, a wallet, or a filing box in a poorly ventilated room, the process happens faster.
